HKS Hipermax IV GT GDB(A-D) Full Kit
Single Tube Damper Design
- Mono tube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and center of gravity gives a more stable ride.
Dust Boot
- Protect the shaft from the flying stones.
PNE Coating
- Using this special surface coating provides 5 times better durability over standard galvanising. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.
M Shaft (?46 normal type)
- With the new design of cylinder shaft since the HIPERMAX M-1, MAX IV increased the cylinder shaft size to have a firm damping even at a little stroke range by optimizing the oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.
Adopted Pillow Ball Upper Mount
- For more accurate and sharp steering.
New Design Needle
- Newly designed needle has been used to revise the very low speed and middle and high speed dampening which is key to a comfort ride.
Reduction of Unsprung Weight
- In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminium. (Not for all vehicles)
30 Step Damping Force Adjustment
- 30 levels of dampening adjustment allow fine tune adjustment for street, circuit winding roads, highway, or the weight of the vehicle.
